it seems to me that the roots of the psychoanalytic distinction between work and play can be traced back to Freud’s two principles of mental functioning (reality and pleasure) that regulate the workings of, respectively, the conscious and the unconscious. Work is presumably part of a cluster that includes reality, survival, and efficiency while play belongs to the realm of pleasure, fantasy, and disorder. Psychoanalysis, with its focus on the unconscious and its commitment to free association, would then be the ally of play and creativity contra work as the most evil of fates.
This, to me, is a little too quick. There is a fair bit of “work” going on in the unconscious, “work” that may have nothing to do with repetition or drudgery: the dream-work and the work of mourning are two classic examples here. These are highly productive processes; they effect change and have little to do with the leisure that has come to define “play.” To put it differently, I see no reason why the workings of the conscious (a logical syllogism or a cost-benefit analysis for instance) should be considered closer to “work” and hence less “pleasurable” then, say, condensation or secondary revision.
I think the distinction between work and play seems self-evident only from the point of view of a structure that has already privileged the one at the expense of the other (either work gives meaning and play is frivolity or work is servitude and play is creativity).
Might it not be more useful here to think in terms of different qualities of work and processes of production, of different types of investments and effects instead?
